' This invention relates to machinery useful in the manufacture of roofin shingles more particularly of the type a apted for dia onal laying and characterized by underfolded corners with attached staple-like securing devices. Such shingles are ordinarily known in the trade as Latite shmgles, and have been extensively manufactured by the machine shown and described in United States Patent No. 1 522,234 to William Freegard and Marius Darrow, dated Jan. 6, 1925. While with this machine the operations ofi stapling and folding are accomplished continuousl and automatically, the pre-cut shingle lanks had to be fed to it individually and by hand, thereby entailing constant attention on the part of an operative. The present invention is directed toward :0 overcoming the disadvantages of hand feeding b provision of automatic mechanism capab e of fox-min and continuously feeding the shingle, b anks from a continuous sheet or web and delivering them to the sta- 5 pling and folding mechanisms of the machine for conversion into completed Latite shingles ready for immediate packing and shipment.

In the drawings, Fig.'I is a plan view of a shingle fabricating machine conveniently embodying the automatic blank forming and feeding mechanism of ourinvention.

Fig; II is an elevation of the machine as viewed from the bottom of Fig. I. I

of the machine opposite to that shown in Fig. II; and,

Fig. IV is a fragmentary elevation viewed in thedirection of the arrows IV-IV in Fi I.

li- Ihe shingle folding and sta ling mechanisms herein comprehensivel, esignated 10 and 11 respectively, will be observed as generally similar to the corresponding mechanisms in the patent to which reference has been made. These, folding and staplin mechanisms 10, 11 are moreover actuate as before, b a drive pulley 12 '(Fi s. I and III) where y motion is constantfy transso mitted, through interposed speed reduction a shaft 28that Fig. III is a partial elevation of the side 1m. mm m, mam.

gearing 13, to the shaft 14 of the upper segmental shingle progressing roll 15 which is attended by a smaller cooperating lower roller 16 with a continuous surface in advancing the shingles S successively to the folding mechanism 10. Intermittent rotary motion is imparted through a mutilated gear 18 and cooperating pinion 19, (Fi II) from the same source to an upper shai 20, which, through an eccentric. 21, reciprocates the upper. stapling die block 22 (Fig. III) relative to the opposin lower stationary die block shown at 23', liiewise as in the patent.

Instead of being individually pro-formed and fed to the machine by hand as heretofore, the shingle blanks S are successivel fabricated from a continuous sheet or we W (Fig I) of suitably prepared waterproofed and mineral surfaced material which is drawn forward from a supply roll (not shown) by a pair of superposed draft rollers 25, 25 that are arranged, in the present instance, at an angle of to the longitudinal center line of the machine and suitably journalled in bearings 26 provided by the machine frame. The draft rollers 25 are driven through spur gearing 27-from erives motion, 'in turn, by virtue of bevel gear coupling at 29 with a stub shaft 30 whereon is mounted a spur pinion 31 which cooperates with a second mutilated driving gear 32 on that end of the shaft 14 of the segmental shingle rogressing roll 15, appearing in Fig. II. he

relation of the intermittent gears 31 and 32 is such that the draft rolls 25 are moved throu h a complete rotation, at each actuation, or diagonal advancement of the web W to an extent corresponding to the width of a shingle S. As a consequence of such diagonal advancement, the corner 0 of the web W (Fig. I) is presented between the upper and lower die blocks 22 and 23 of the staple forming and applying mechanism 11, while the yet uncut blank is at the same time properly allocated in readiness to be engaged by the main progressing rollers 15, 16 and passed to the folding mechanism 10.

During the dweil which follows shifting the se blades 35 of the web W as just described, the mechanism 11 is actuated to apply a staple across the forward comerC of theweb W in precisely the same manner as set forth'in the patent, supra; and the blank shingle S is concurrently severed from the web W by shearing mechanism,

ings. As shown, this shearing mechanism 34;

comprises a pair of opposing cutting blades 3-5, 36 between which the end of the web W is passed incidental to its feeding, one of being fixedly supported by the machine frome while the companion blade-3% is secured in a movable holder 37 with opposite ends fulcrumed at 38, 38 on said machine frame, and an actuating'link connection 39 with an eccentric 40 on the the progressing rollers 15,16, and by'thern advanced to the mechanism 10 for progresretrovertive bending of the stapled and final scoring of the resulting 7 corner C 'mittently driven, speed reducing gears d6 (Fig; l), from a upper shaft 20, hereinbetore rei erred to.

Immediately upon the consummation of the foregoing contemporaneous operations, the

severed shingle blank S is gripped between sive 1 fold to render the crease permanent,

In lieu of the arrangement of the patent, feeding of the metallic ribbon M from which the staples are formed is preferably effected by actuating means operativel'y co-ordinated and timed with the drive of the main advancing rolls 15, 16 and the web drawing rollers 25, To this end we provide a pair of superposed nip rollers a5-4=5, (Fi s. l and HI) between which the ribbon passed enroute from a source of continuous supply not shown, said rollers being interthrough the medium of shait i? that is dependent r movement upon a bevel gear connectionat 4:8 with one cluding means for intermittently feeding a a strip of material in the direction of its length, a knife arranged to sever'the strip on a transverse line to form a shingle therefrom while the strip is stationary, means for operating on a corner of a shingle, and means for intermittently feeding a severed is} shingle in the direction of its'diagonal and vlength, a which is generally in-- dicated at 34 in Figs. 1 and 1V of the draw-j diagonal companion shaft 19. At the opintense at an an is to the direction of feed of the strip to t' e said operaEi ng means,

2. A shingle manu acturing machine including means for intermittently feeding a strip of material in the direction oi its knife arranged to sever the strip on a transverse line to form-a shingle there from while the' strip is stationary, means i for stapling a'corner oi a shingle substantially concurrently with its severing, means for operating on the stapled corner of a shingle, and means'for intermittently feeding a severed shingle in the direction of its and at an angle to the direction of feed of the strip to the said operating means.

' In testimony whereof, we have hereuntof signed our names at Madison, lili,

day of July, 1926. WILLIAM J. HARE, FRED G. GRUNEMEYER. FRANCIS B. WATKllNS Mannie snannow.
